Littelfuse Announces Arrays of Automotive TVS Diodes to Ensure Highest Reliability in the Most Rough Environments

One-way or two-way ESD and surge protection optional

Littelfuse Corporation today announced the launch of two AEC-Q101-compliant transient-suppression diode array (SPA® diodes) families. The AQHV and AQHV-C series are designed to provide extremely fast-acting, high-performance overvoltage protection devices that are best suited for power interfaces, passenger charging interfaces, and LED lighting modules and low-speed I/O.

AQHV/AQHV-C Series TVS Diode Arrays

Both series of products can safely absorb the highest level of repetitive electrostatic discharges higher than the international standards without deteriorating performance, and can safely dissipate up to 8A (AQHV12 series) at a very low clamping voltage Inrush current.

Typical applications for AQHV and AQHV-C series TVS diode arrays include:

ESD protection of automotive electronics
LED lighting module
Mobile/handheld devices
CAN bus (telewire)
LIN Bus RS-232 and RS-485 Interfaces
General low speed I/O
Portable instrument

"As a device that meets the requirements of AEC-Q101, the AQHV and AQHV-C series can ensure the highest reliability in the harshest environments," said Tim Micun, Director of Littelfuse's TVS Diode Array (SPA® Diode). "This makes it an excellent choice for designers who need to replace passive ESD protection devices or deploy protection devices on printed circuit boards."
The AQHV and AQHV-C series of TVS diode arrays have the following key advantages:

Compared to alternative technologies, the lower dynamic resistance lowers the clamping voltage by 60%, which is ideal for protecting modern electronic products using small ICs.
The silicon diodes used in the structure can handle >1000 ESD shocks or transient surges without degrading performance, compared to alternative technologies that have inherent internal wear defects.
